Piston Ring Function and precautions

The basic function of piston ring: 1. Airtight function: it can prevent the leakage of gas in the piston cylinder; 2. Heat conduction: the high heat generated after the explosion can be transmitted to the cylinder wall by the piston ring to achieve the effect of dispersion; 3. Lubrication and oil scraping: it can prevent excessive oil from entering the combustion chamber and fully lubricate the cylinder wall; 4. Maintain the movement direction of the piston and select the best piston ring for the engine. In the whole engine cylinder, the piston ring does not occupy a large volume, so the layman will mistakenly think that it is a simple part. In fact, the role of the piston ring is as important as the valve in the heart. The choice of non-friction will cause bad phenomena such as eating engine oil, scratching the cylinder wall, reducing horsepower, consuming fuel, and increasing noise. Due to the insurmountable relationship between technology and equipment, ordinary small factories with miscellaneous brands not only produce inferior products with poor appearance, but also check carefully some subtle characteristics, which are rough and unstable, or violate design principles; After use, the engine obviously cannot maintain the original design performance and causes great damage to the engine. Therefore, the choice of piston rings produced by professional manufacturers with world-class brands can guarantee stable quality, which is also the only way to maintain engine performance and prolong service life. The meaning of piston ring engraving: the engraving on the side of the piston ring joint has two functions: one is to distinguish the direction of the piston ring, and the other is to clarify the size, location and manufacturer of the piston ring. . . . Wait. Generally speaking, the functional design of the piston ring has its directionality due to its cross-sectional shape, so when installing the piston ring, the engraving side must be oriented toward the top of the piston, otherwise it will not only fail to function, it will also hurt the whole cylinder. The right mark on the periphery of the piston ring joint is usually an identification mark of the manufacturer, such as' r '(On behalf of Taiwan research and manufacturing) Sometimes, for easier distinction, the position of the piston ring will be indicated by' 1r' and' 2r', or the position of the piston ring will also be indicated by' RN', representing the use of RIK-20 material. Matters needing attention in piston ring fitting: 1. The installation of piston ring shall be carried out with special installation tools, and the groove of piston ring shall be cleaned before installation. 2. Assemble from the bottom ditch in sequence, and note that the engraving side should face the top of the piston ring. 3. The joints of each piston ring must be staggered (Avoid a straight line) About 15, and avoid the tip hole and 90. 4. Assemble steel combined oil ring (VENT)Note: 4-1. Put the spacer into the ring groove first, and the tip of the joint is facing the fixed part of the piston ring. It is strictly prohibited to overlap left and right. 4-2. Then install the two pieces of RAIL, and remember to stagger the joint clearance of the three to each other by about 15 degrees. 4-3. After installation, make sure that the ring can be rotated horizontally by hand. 5. When installing the piston ring with COIL or EXPANDER, pay attention to make the joint clearance between the oil ring and COIL or EXPANDER 180 ° (Opposite side)

High-End Product Introduction: CKS (CID) Piston Ring

Our CKS (CID) Piston Ring adopts upgraded Chromium-based Composite Ceramic technology, an industry breakthrough that meets Euro IV emission standards and delivers double the wear resistance of conventional chrome plating.

The process forms uniform mesh textures inside the outer chrome layer, filled with wearresistant particles to enhance anti-friction performance. The mesh structure also provides excellent oil storage capacity, effectively lowering friction and protecting cylinder liners. The ring body is strengthened by nitriding treatment, boosting hardness, strength and impact resistance.
Piston ring is broken what symptom phenomenon does leak have?
Piston ring is broken what symptom phenomenon does leak have?
The bad piston ring​ may be related to the air leakage caused by its wear or coke connection with the piston ring groove. If after cutting off a cylinder, the exhaust gas no longer from the oil or vent vent, the cylinder piston is not good use.
What is the  role of piston ring?
The piston ring is the core component of the fuel engine. It seals the fuel gas with the cylinder, piston, and cylinder wall. Piston ring functions include four functions: sealing, adjusting engine oil (oil control), heat conduction (heat transfer), and guide (support).
